Really cool problem that climbs out from under a roof with pockets, a long and satisfying dead-point and slopers that benefit from cooler weather! But be careful, it is slow-drying and may be fragile.
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
